I SLUIB-CATCHER.

Specification of Letters Patent.

Patented Sept. 20, 1921.

Application'flled September 18, 1920. Serial No. 410,637.

the dev ce out of, its normal position, this result being accomplished without changinglthe parallelism of the walls of the slit.

y slub catcher more specifically comprises a bracket havin an integral resilient yoke, the branches 0 which are provided with lateral extensions which form between them the slit for the passage of the yarn; means being provided, such for instance, as an adjusting screw which spans the yoke members, for springing one of the members 2 out of its normal position toward the other member to narrow the slit for adapting it to different sizes of yarn.

A further object is to combine the slub catcher with a yarn tension.

A practical embodiment of my invention is represented in the accompanying draw.-

in s, in which,

l igure 1 represents the slub catcher in top p an.

I Fig. 2 represents the same in side elevation.

Fig. 3 represents a rear elevation.

Fig. 4 represents a front elevation.

Fig. 5 represents a sectiontaken in the plane of the line V-V of Fig. 1-.

The bracket is preferably a casting which comprises a resilient yoke, the lower branch of which is designated by 1 and the upper branch by 2. These two branches at their free ends are provided with lateral extensions 3 and 4 respectively, forming betweenp them .a slit 5 for the passage of the yarn. These lateral extensions 3 and 4 may be provided with downwardly and upwardly extended ears 6 and 7 respectively. A pin 8 projects downwardly from a lug 9 on the back of the upper lateral extension 4, across larged portions of the yarn,

the slit 5, which pin serves as a guide for the yarn passing through the slit.

' The means which I have shown for springing the upper branch 2 of the integral resilient yoke out of its normal position to vary the width of the slit 5 without changing' the parallelism of its walls is herein shown as an adjusting screw, the shank 10 of which passes through the upper branch 2, across the yoke into screw-threaded engagement with the lower branch 1, the head 11 of which screw is preferably countersunk in a recess 12 in the upper branch 2. As the device is shown, the screw is arranged to spring the 'u per branch 2 toward the lower branch 1 0 the yoke to narrow the yarn slit, the spring in the upper branch 2 serving to widen the said' slit as the adjusting screw is unscrewed.

The bracket may be supported in any suitable manner on the bar 13 of the ma= chine, as for instance, by providing the lower branch 1 of the yoke with a hollow lug 14 through which the bar 13 extends, a set screw 15 being provided for securing the bracket on the bar.

A tension for the yarn is carried by the upper branch 2 of the yoke and comprises generally a vertical pin 16 on which is} loosely mounted a wei tween which and the tab e 18 the yarn passes on its way to the slit 5. A suitable guard 19 is secured on the pin 16 by a set screw 20. A ide finger 21 projects forwardly from the bracket in position to guide the yarn to the tension.

It will be seen from the above description that I have provided a device which will engage bunches, slubs, knots or other enwhich device have its slit enlarged or ensmalled to am of different sizes, the means for width of the slit being exle and capable of adjusting may suit varying the tremely sim the width 0 arallelism of its walls.

It will also be seen that the device is extremely simple, having a minimum number of parts for accomplishing the results set forth. It is evident made in the construction, form and arrangehted disk 17, be-

the slit without changlng the i that various changesmay be ment of the several parts without departing from the spirit and'scope of my invention; hence I do not wish to limit myself to the particular construction herein shown and described; but- What I claim is:

1. A slub catcher comprising an integral resilient yoke, the branches of which have between them a slit for the passage of the yarn, said slit having parallel walls, and means for springing one of the branches out of its normal position to vary the width of the slit and at the same time to maintain the parallelism of its walls.

2. A slub catcher comprisin an integral resilient yoke, the branches 0 which form between them a slit for the passage of the yarn, said slit havin'g parallel walls, andmeans for springing one of the branches toward the other branch to narrow the slit and at the same time to maintain the parallelism of its Walls.

3. A slub catcher-comprising an integral resilient yoke, the branches of which have lateral extensions forming between them a slit for the passa e .of the yarn, said slit having parallel walls, and means for springing one of the branches out of its normal position to-vary the width of the slit. and

at the same time to maintain the paralleL' ism of its walls.

branch tonarrow the slit and at the same,

time to maintain the parallelism of its walls.

5. A slub catcher comprising an integral resilient yoke, the branches of which form between them a slit for the passage of the yarn, said slit having parallel walls, and a! screw spanning the branches for springing one of the branches out of its normal position to vary the width of the slit and at the same time to maintain the parallelism of its walls.

6. A slub catcher comprisin an integral resilient yoke, the branches 0 which form between them a slit for the passage of the .yarn, said slit having parallel walls, and a screw spanning the branches for springing A one of the branches toward the other branch to vary the slit and at the same time to maintain the parallelism of its walls.

In testimon that I claim the foregoing as my invention, I have signed my name this 9th day of September, 1920.
